PADLOCK.

SPECIFICATION forming part of letters Patent No. 410,027, dated August27, 1889.

\ Application tiled March 16 1889. Serial No. 303,576. (No model.)

T0 all whom it may Concern.-

`Be it known that I, MICHAEL RUECKERT, a citizen of the United States,and a resident of St. Marys, in the county of St. Genevieve and State ofMissouri, have invented certain new and useful Improvements in Padlocks;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which- Figure l is a side view of my improved padlock closed.Fig. 2 is a similar view taken at right angles to the View shown in Fig.l. Fig. 3 is a longitudinal vertical sectional view showing the lockclosed. Fig. 4 is a perspective view of 'the lock as it appears whenpartly open. Figs. 5 and 6 are perspective views of the upper and lowerhalves, respectively. Fig. 7 is a perspective detail View of theinterior of the movable locking thimble 0r sleeve. Fig. 8 is a similarview of the threaded key-pin. Fig. 9 is a similar view of the key usedin conjunction with that form of pin, and Fig. 10 represents a`cross-section on line :c in Fig. 1.

Like letters of reference denote corresponding parts in all the figures.

This invention relates to padlocks of the class known as link-padlocksor lockinglinks, and has for its object to produce a lock which whileinexpensive and simple in its construction shall yet be very strong anddurable and easyl of manipulation.

To this end my improvement consists in the detailed construction andcombination of parts of a lock of that type, as will be hereinafter morefully described and claimed.

Reference being had to the accompanying two sheets of drawings, theletters A and B designate the two halves of the link proper, the part Abeing provided on one side with a fixed sleeve C, on the inner side ofwhich are two projecting studs .e c, opposite to each other, while thelower end of the other side is provided with a so-called bayonet-catcha. The other half part B has one of its ends grooved with two grooves band b,'and is notched, as shown at d and d', Fig. 6, for the insertionof the studs or projections c c, when the grooved arm of part B isinserted into and interlocked with the iixed sleeve C of the part A.Thus it will be seen that the two parts A and B are swiveled togetherdetach- `ably by means ot sleeve C. The other arm cess a in part B isbored a screw-threaded aperture D, having an enlargement D at its outerend for the insertion of the threaded keypin E, (see Figs. 8 and 10,)which has a head e, of such a shape that it will t into the key used foropening or closing the lock, one form of which is shown in Fig. 9, andis provided with an offset f on one side, which, by striking against aprojection within the en largement or key-hole D', will limit the playof the threaded key-pin to either side, thereby preventing it from beingscrewed out too far and becoming lost. Upon the same part B is placedth'e sliding locking-thimble F, which has an aperture G, adapted toregister with the key-hole D when the sleeve is turned into its properposition for opening or closing the lock. On the inside of this sleeve,Fig. 7, is a projecting stud g, adapted to t into the`bayonet-catch aand its registering-extension a', and also a groove or recess 7L,adapted to receive the inner end of the threaded keypin E when this isscrewed home by turning it with the key.

From the foregoing description, taken in connection with the drawings,the operation of this device will be readily understood. The lock beingopen, in the position shown in Fig. 4, if it is desired to lock it theswiveled part B is turned until its free end, carrying thelocking-thimble F, registers with the corresponding arm ot' part A, inwhich position the lower notch of the bayonet-catch a in part A willregister with the recess a in part B, into which the inside stud g ofthimble F projects. The parts being in this position, the -thimble ispushed up upon part A, so as to cover the bayonet-catch, and then turnedto one side, causing the projection g to enter and engage the uppernotch of the bayonetcatch, and thereby locking the two halves A and Btogether. Turning the thilnble into this position Will bring itsaperture G opposite to the key-hole D', and by noW inserting the key andturning the key-pin E in its threaded hole its inner end Will projectinto the groove or recess-h in thinible F, so that this cannot be sliddown upon its appropriate arm of partB to unlock the lock. After thisthe sleeve is again turned, so as to cover the key-hole, when theoperation of locking is completed. To unlock, this procedure is simplyreversed.

Hav'ing thus described my invention, I claim and desire to secure byLetters Patent of the United States- In a padlock, the combination ofthe inein- MICHAEL RUECKERT.
